Myelofibrosis is a serious bone marrow disorder that disrupts your body's normal production of blood cells. The result is extensive scarring in your bone marrow, leading to severe anemia, weakness, fatigue, and often, an enlarged spleen and liver. Myelofibrosis is an uncommon type of chronic leukemia — a cancer that affects the blood-forming tissues in the body. Myelofibrosis belongs to a group of diseases called myeloproliferative disorders.
In Argentina, 36 pts with myelofibrosis, including primary MF (PMF) and post polycythemia vera (PPV) received ruxolitinib through CUP regardless of JAK2 mutational status. Study period: September 2011 to June 2013. Splenomegaly was evaluated by physical exam, and constitutional symptoms were categorized as present or absent. Retrospective analysis was performed based on data at baseline (n 36), after 3 months (n 30), 6 months (n 24) and 12 months (n 14).
In the past, the treatment of myelofibrosis has depended on the symptoms and degree of the low blood counts. A long-term remission is possible for some patients with bone marrow transplantation. Such treatment should be considered for younger patients and some others. Other treatment may involve:Blood transfusions and medicines to correct anemia, Radiation and chemotherapy, Medicines to target a genetic mutation, Splenectomy if swelling causes symptoms, or to help with anemia.
